ADJUSTABLE DECKLE FOR WET-CYLINDERPAPER-MACHINES.

To all whom it may concern: 3

Be it known that I, ALTON STAMETs, a citizen of the United States, and aresident of Gloucester City, county of Camden, State of New Jersey, haveinvented certain Improvements in Adjustable Deckles for Wet- CylinderPaper-Machines, of which the following is a specification.

One object of my invention is to improve the construction of cylinderpaper machines,

' by making the deckles laterally adjustable :so as to regulate thewidth of'th'e sheets of paper formed upon the cylinder. A further objectof the invention is to provide means for making a tight joint betweenthe deckle and the cylinder so as to prevent the escape of the pulp atthe space in the :side beyond the deckle.

A still further object of the invention is to provide means forsimultaneously adjusting the deckles of paper machines as fullydescribed hereinafter, reference being had to the accompanying drawings,1n wh ch Figure 1, is a side view, partly in section,

showing a set of three cylinders used in connection-with paper makingmachines; Fig. 2, is a planview' of one end of a series of paper makingmachines; Fig. 3, is a sectional plan view of a part of one of'themachines; Fig. 4, is a detached perspective view'of the deckle frame;Fig. 5, is a perspective View of one of the deckle bands; Fig. 6, is aperspective View of the U-shaped lining; Fig. 7 is a view of amodification of a the means for adjusting the, deckle frames; and Fig.8, 1s a vlew showlng guides for the deckle band.

chines.

I have'illustrated a set of three machines located in lineone'with'another, so that a three-ply sheet of paper can be formed byhaving a screen 3 thereon. The cylinder is mounted on a transverse shaft4, and any suitable means is provided for rotating this shaft. The vatis supplied. with the paper' stock and a suction device is provided forcreating a suction within the cylinder so that, as the cylinder rotates,a certain amount of the stock is drawn up the screen.

'stock can pass beyond the frames 5.

"stock from the screen as the cylinder rotates forming thesheet. Inorder to regulate the Specification of Letters Patent. l t t d N 231915; Application filed July 22, 1914. Serial No. 852,441.

width of the'sheet a deckle is located on the side of the cylinder.Extending across each cylinder, above the liquid line, is a felt andthis roll. A spray pipe is used to spray 'above thisfelt is the ordinarycouch roll. Q The paper 1s drawn from the cylinder under water on thecylinder so. as to. keep it clean after the paper has been removed. Allof the above described'mechanism is common to this type of machine andthe primary object of my invention isto improve the form ing the decklessimultaneously. 7

Located in each end of the vat 1 is a U- shaped lining 1, preferably of.brass: or

' bronze. The liningis flanged and the flanges of deckle and to providemeans for adjusta V grooved, as at 7, to receive a segmental strip offelt 8, or other suitable material. The felt extends above the surfaceof the liquid containing the paper stock;

Mounted on the upper end of each frame 5 are two rollers 9 over whichpasses the endless deckle band 11. This band extends between the wirescreen 3 and the felt 8. The joint between these two is such that nopaper The other portion of the band hangs freely with- .in the vat, asshown in Fig. 1. Anti-friction rolls 12 are located at intervals so asto guide this run of the band. By this construction the pulp is retainedin the space between-the two deckle frames.

Inorder to move the deckle frames in. unison toward and from each other,so as to increase thewidth of the paper'being formed on the cylinders 2,I mountthree screw rods 13 in bearings 15 and extend these throughstuffing boxes 14 secured to the outside of the vats, and on the deckleframe 5 are nuts 16 through which the screws eXtend,so that, on turningthe screws in unison, the deckle frame will be moved toward-and from the20. This shaft extends along the full length of the series of vats, sothat, on turning the shaft 19 by the hand wheel :21, all 7 the sprocketwheels will be turned in unison on that side of the several vats and,asthere is a duplicate of thismechanism on the opposite side of the vat,the deckle frames at each,

side are independently adjusted.

In place of the construction illustrated in Figs. 1 and 2, I may use theconstruction,

illustrated in Fig. 7, in which the screw 13" is secured to thedeckleframe 5 and passes through a stuffing box 1 1 in the casing, and

the sprocket Wheel 17? is in the form of a nut and turns on the screw. 7

15 is a bracket to hold the sprocket wheel in position. On turning thesprocket'wheel 17 the deckle frame 5 will be moved in either direction.j e I In Fig. 8, I have shown a flange 5 on the deckle frame to hold thedeckle band on the roller 9, if it is found desirable. The roller mayhave a certain amount of side play on its bearing to allow the band torun free.

1. The combination in a cylinder paper machine, of a vat; a cylindermounted therein and having a screen; a deckle frame,

partly inclosing the cylinder and fitting the vat forming a partition;an endless deckle band" carried by the frame, one portion of the bandbearing against the cylinder; and yielding meanson the frame bearingagainst the band so as to make a tight joint between the frame and theband to prevent the paper stock from passing beyond the deckle frame.

2. The combination of a vat; a cylinder mounted therein; a screen on thecylinder; a deckle frame fitting the side walls of the V vat at or aboutthe liquid line and having a segmental groove; a felt mounted in thegroove extending above the liquid line; with anendless belt supported bythe frame, one portion of the belt extending between the cylinder andthe segmental felt, the other portion of the belt being-out of contactwith the cylinder.

3. The combination of a vat; a pylinder mounted in the vat; a deckleframe located in the cylinder, the ends of the deckle frame restingagainst the sides of the vat; two

rollers mounted in the upper portion of the deckle frame, one at eachside of the cyl inder; an endless loand arranged to pass around bothrollers and looped, the inner loop bearing against the cylinder, theouter loop being free of the cylinder; and a seg-' mental strip of feltcarried by the frame and bearing against the inner loop of the band.

6. The combination of a vat; a cylinder mounted therein; twodeckleframes within the vat extending from oneside thereof to the other andpartly encircling the cylinder; an endless band under the c linder andcarried by the deckle frame and, fitting between the frame and thecylinder so as to make a tight oint; nuts on theframe; screwshaftscarried by the vat and extending through the nuts, said screw shaftsbeinggeared to t gether; a set of screw shafts for each deckle frame oneset bein located on one side of the vat and the other on the oppositeside;
